Module extras 

CloudFormation handlers added to close the conformance gap. Change sets, stack sets / instances, types, generated templates, resource scans, drift detection, refactors, hooks, exports, imports, stack events, organizations access, stack policies, termination protection, and validation operations.

These handlers persist into per-account state via the generic extras: HashMap<category, HashMap<id, Value>> store on CloudFormationState. They return real XML responses with stable IDs so SDK callers can chain operations (e.g., CreateChangeSet -> DescribeChangeSet -> ExecuteChangeSet).
